Holograph, signed.

In this letter, Samuel Joseph May says that he was unable to come to the anti-slavery fair because he had a previous engagement to lecture in Plymouth. He contends "that the cause of freedom and of anti-slavery are, in this country, identical---..." He refers to a "cowardly assault" upon the rights of the people made by Gov. Edward Everett. He received a letter from William Ellery Channing. He calls Channing "unfair in his judgment of the Abolitionists---and yet he has accorded them some high praise." He wants black people to present a "petition to the Legislature of Massachusetts setting forth the grievances they suffer under the operation of the laws of the southern states, and praying the Legislature to remonstrate in their behalf with the Legislatures of those states."
